I'm really happy that you took the time to read it, especially such a long post about such a tiny engine haha.
I decided to make it that long because I wanted to tell the whole story, with all the little details—things that even I might forget in the future. It's meant to be a record of the journey. Ten years from now, I want to come back, read it again, and feel nostalgic. I know it's not the most accessible read because of its length, so the fact that you actually read it means a lot to me. Thank you so much for that, and thank you as well for all of your contributions to the engine.
By the way, what's your background? Are you a programmer too? What part of the world are you from? Diego and I are both Brazilian, so we speak Portuguese, but here on itch.io I translate everything into English.
I'm also excited about the engines you mentioned. I'll definitely check them out—combining Twine and Bitsy sounds like a brilliant idea.
